If you install the gnome-power-manager by default, gnome-brightness-applet will be installed in /usr/lib/gnome-power-manager/. You can try this by 'sudo apt-get install' in lucid and you can select brightness applet from gnome-panel.If you cann't find this directory in your system, I think you have modified something during your building package steps and also you can try to new this directory and move gnome-brightness-applet here, but this is only a test.
Hi Lars,
If you install the gnome-power-manager by default, gnome-brightnes s-applet will be installed in /usr/lib/ gnome-power- manager/ . You can try this by 'sudo apt-get install' in lucid and you can select brightness applet from gnome-panel.If you cann't find this directory in your system, I think you have modified something during your building package steps and also you can try to new this directory and move gnome-brightnes s-applet here, but this is only a test.
